Objectives: To examine the utilisation pattern of accident and emergency services and to study the possible impact of a user-fee policy on non-emergency attendances in Hong Kong.
Design: Retrospective study.
Methods: Four different scenarios are postulated to examine the impact on the number of accident and emergency attendances of a user-fee policy from 2000 to 2029. Patient volume data of accident and emergency attendances for 2000 were made available by the Hospital Authority of Hong Kong.
Results: Non-emergency use of the accident and emergency services is the main cause of over-utilisation and contributes to more than 70.0% of its use. Only 22.0% of patients attending accident and emergency departments were admitted to a ward for further treatment. By 2029, the number of accident and emergency attendances would increase by more than 47.0% if the present utilisation pattern prevails. However, if patients at triage levels 3, 4, and 5 were discouraged from using the accident and emergency services, the number of attendances would decrease by 76.4%.
Conclusion: The proposed user-fee policy would act as a deterrent by preventing unnecessary use of accident and emergency services. However, the use of out-patient services may be increased as a result and attendance should be carefully monitored. Community health education and civic education relating to abuse of accident and emergency services would be effective in reducing over-utilisation of these services.
